周博文: trading record in brief
周博文 appears in our data through filings on 億光 shares, published by TWSE / TPEx (MOPS). Between 3 January 2017 and 4 December 2025, the trades on record add up to 3 filings.
The filings describe grants, exercises and other transfers rather than trades on the open market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
On 4 December 2025 came the latest disclosure, a transaction in 億光. Most trades are made public on the day they happen. Until a filing is published, the market cannot know about the trade. Every figure here comes from the filings published by TWSE / TPEx (MOPS) and describes the past, not future prices; it is not investment advice.
